## func azure functionapp publish

In general, the deployment output needs to be cleaned up a bit. We might not want to hide them by default as we don't want folks to have to re-deploy with `--verbose` to see errors.

Display a summary after deployment that outlines important things such as:

* What function app it was deployed to
* How long the deployment took
* Deployment method and info relevant to the method: e.g., run from package with the location of the package
* List out functions (both HTTP and non-HTTP)
